Cardiologist | Specialist in Arrhythmias, Electrophysiology and Cardiac Pacing

Dr Javier Ramos Maqueda

I am Javier Ramos Maqueda, a cardiologist specialising in arrhythmias, cardiac electrophysiology and pacing. My career has been dedicated to the diagnosis, treatment and study of heart rhythm disorders.

I currently lead the Arrhythmia Unit at Hospital Clínico Universitario Lozano Blesa and the Arrhythmia Unit at Clínica HLA Montpellier, both in Zaragoza. I also serve on the Board of the Cardiac Rhythm Association of the Spanish Society of Cardiology, actively contributing to the development, promotion and advancement of our specialty.

My work is built on three inseparable pillars: clinical excellence, scientific research and teaching. They share a common aim: to advance cardiology through the treatment of heart rhythm disorders and offer every patient the best possible care.

Clinical Experience, Teaching and Research

Clinical experience and patient care

I have nearly 10 years of experience in diagnosing and treating heart rhythm disorders. Over that time, I have developed a highly specialised clinical practice, incorporating technological advances and innovative techniques in electrophysiology.

Throughout my career, I have combined clinical practice with the leadership of teams and specialist units. This has given me a comprehensive understanding of the management of heart rhythm disorders, from diagnosis to the selection of the most appropriate treatment strategies.

I see medicine as a combination of scientific knowledge, clinical experience and compassionate care. I am committed to offering each patient personalised, supportive and thorough care, based on the best available scientific evidence, and to finding the diagnostic and treatment options that best meet their needs.

Research and scientific innovation

I hold a PhD in Medicine from the University of Granada, awarded the highest distinction (sobresaliente cum laude), and my research focuses on improving the understanding, diagnosis and treatment of heart rhythm disorders.

I am a member of the Biomedical Signal Interpretation and Computational Simulation Group (BSICoS), a research group linked to the University of Zaragoza and the Aragon Institute of Engineering Research (I3A). I currently supervise several doctoral theses at the University of Zaragoza.

My research track record includes more than 25 articles published in high-impact scientific journals, securing competitive funding for 7 international, national and regional research projects, and participation in more than 25 multicentre research projects.

For the international INSIDE-HEART project, I serve as principal investigator on behalf of the Instituto de Investigación Sanitaria Aragón (IISA). This collaborative project is funded by the European Union through the Marie Skłodowska-Curie Actions (MSCA), one of the European Union’s most prestigious research funding programmes.

Teaching and training future professionals

I combine my clinical and research work with a strong commitment to teaching. I am currently an associate professor at the University of Zaragoza and supervise cardiology residents at Hospital Clínico Universitario Lozano Blesa in Zaragoza. I also speak regularly at major conferences of the Cardiac Rhythm Association of the Spanish Society of Cardiology.

Through teaching, I take an active role in educating future doctors, training new cardiologists and supporting the continuing education of leading cardiologists. I support them in their scientific, clinical and professional development.

Passing on knowledge, sharing experience gained in clinical practice and encouraging critical thinking, scientific rigour and excellence in patient care are essential responsibilities of our profession. They are also among the best ways to train highly skilled professionals and ensure high-quality healthcare for future generations.

My commitment to cardiology

My career is built on three pillars: patient care, research and teaching. My aim is to continue developing professionally and contribute to advances in cardiac electrophysiology through all three areas.

In patient care, my priority is to provide personalised, compassionate medical care of the highest quality, offering the most appropriate and up-to-date diagnostic and treatment options.

In research, my commitment is to keep playing an active part in developing new knowledge and strategies that improve the diagnosis and treatment of heart rhythm disorders.

As a teacher, I want to continue sharing my knowledge, experience and values with future generations of doctors, cardiologists and electrophysiologists. This helps prepare professionals committed to clinical excellence and scientific rigour.
